Everytime i go skiing it's a road trip (3 and a half hours) so i just smoke and talk to the driver about random incoherent shit that goes from tangent to tangent to tangent. good system. But when i have to hitch a ride with people i don't really know, there are some things that are insignificant but annoy the hell out of me.
1) people sleeping the whole way there. A quick 1/2 hour nap is cool but not the whole time. Shotgun MUST STAY AWAKE.
2) people who forget a bandana on a wet windy day and use your backup you where planning on useing the second half of the day...goes for any accessory.
3) people who take arguments too far. Long road trips will have debates/discussions, about random shit, but when people take it too far and won't let it go, or attack someone personally, it just harshes everyones trip.
4) drivers who refuse to make stops. Too many stops suck, but a munchy/monster break or piss break is clutch every few hours or so.
